Calculating $11^{81}$ gives us 85 digits.
Find the number of digits in 11 to the 81th power
Let's actually ask for it.
Let's calculate the common logarithm of 11 to the 81th power.
\begin{eqnarray}
\log_{10}11^{81}&=&81 \log_{10}11\\
&=&81\times 1.0413\cdots\\
&=&84.352
\end{eqnarray}
In other words,
We can say that $11^{81}=10^{84.352}$, so we know that $11^{81}$ has 85 digits.
How to find the number of digits
To find the number of digits in $11^{81}$, use common logarithms.
By using the common logarithm, we can calculate the power of 10, so we know the number of digits.
For example, $10^1=10$ is 2 digits.
On the other hand, $10^2=100$, so 3 digits.
So $10^a$ has $10+1$ digits.
If $a$ is a decimal, the number of digits is the integer part plus 1.
$a=11.34$ will be 12 digits.
